This method instructs the object to initialize itself by using the properties available in the property bag, notifying the provided error log object when errors occur.

Syntax

HRESULT Load( 
  IPropertyBag* pPropBag, 
  IErrorlog* pErrorLog 
);

Parameters

  • pPropBag
    [in] Address of the caller's property bag, through which the object can read properties.

    This cannot be NULL.

  • pErrorLog
    [in] Address of the caller's error log, in which the object stores any errors that occur during initialization.

    This can be NULL. If it is NULL, the caller does not receive errors.

Return Value

The following table shows the return values.

Value Description

S_OK

The object successfully initialized itself.

E_UNEXPECTED

This member was called after IPersistPropertyBag::InitNew had already been called. These two initialization methods are mutually exclusive.

E_POINTER

The address in pPropBag is not valid and therefore the object cannot initialize itself. If the value of pPropBag is NULL, the method returns E_POINTER.

E_FAIL

The object was unable to retrieve a property that is necessary for the object's successful operation. The object was unable to initialize itself completely.

Remarks

All property loading must take place within the IPersistPropertyBag::Load function call because the object cannot hold the IPropertyBag pointer.

E_NOTIMPL is not a valid return code because any object implementing this interface must support the entire functionality of the interface.

Requirements

Header ocidl.h, ocidl.idl
Library ole32.lib, uuid.lib
Windows Embedded CE Windows CE .NET 4.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
